Topline results from the pivotal phase III KEYNOTE-859 trial investigating Keytruda (pembrolizumab), in combination with chemotherapy for the first-line treatment of patients with human epidermal growth factor receptor 2 (HER2)-negative locally advanced unresectable or metastatic gastric or GEJ adenocarcinoma, were positive.
Perioperative treatment with Imfinzi (durvalumab) in combination with standard-of-care FLOT (fluorouracil, leucovorin, oxaliplatin, and docetaxel) chemotherapy demonstrated a statistically significant and clinically meaningful improvement in the key secondary endpoint of overall survival versus chemotherapy alone, according to MATTERHORN phase III trial results.
